    ath79: DTS improvement for buzzer on RB951G-2HnD
    
    Mikrotik RB951 router has a buzzer on the board, which makes annoying noises
    due to the interference caused by PoE input or Wifi transmission
    when no GPIO pin state is set.
    I added buzzer node to device's DTS in order to set deault level to 1
    and to provide easier access for it.
